The global network access control (NAC) market is expected to generate revenue of $3 billion between 2016 and 2020, according to Technavio. A rise in malware attacks on enterprise networks has boosted investments in NAC products to ensure authorized access to data.

The Americas dominates the global market for NAC solutions, the firm says, accounting for about 58% of the overall market share. High adoption of Internet of Things (IoT) in machine-to-machine (M2M) communications is propelling the NAC market in the Americas, Technavio notes.

The U.S. is the major revenue contributing country in the Americas. Vendors are integrating NAS with other security products such as firewalls, mobile device management, and security incident and event management to offer better data security, support and functionality.

Several vendors are also focusing on developing next-generation NAC offerings due to the surge in mobile applications and bring-your-own-device (BYOD) policies. The market is seeing increased use of cloud-based NAC services, which include managed services, authentication processes, video management systems and biometric data storage.

Cloud-based NAC can enterprises store large amounts of confidential data at reasonable costs, Technavio says.
